Imagine your iCal appointments scrolling across your Screen Saver
Macintosh iCal users know that screen savers have come a long way since the days when those kitschy winged toasters used to float around the screen when your computer was resting. But even most savvy Macintosh users don’t know that screensavers used to serve a technical function. Screen savers first came about in the days when computers had monochrome CRT monitors. They were designed to prevent phosphor burn-in, and those screensavers served their purpose well, flying toasters, swimming fish, tail-wagging puppies and all.
